"First of all, he had a great attitude doing work on a Sunday of the Labor Day holiday. Then he performed the task of replacing a toilet and two new valve stems, in a really efficient and professional way. Just cannot say enough about his skill and friendliness, and would recommend him with my highest regards!"

"In response to my 'phone call a man came to my house in less than an hour. After we agreed on the work to be done, he got to work immediately, replaced one toilet and repaired another in a few hours. It couldn't have been easier or more efficient."

"This guy is AWESOME. We got Jay in for a fairly simple plumbing job in the new bathroom, then we decided we wanted to get some new toilets, Jay said yes of course and it was done I also asked for new gas line no problem he said fixed. Then we asked him to fit three new vanities which she did efficiently and finally we asked the impossible about the new shower extending it out and he found a way. What can I say he did everything asked at a price that was very good he was an awful lot cheaper than the big boys because he doesn't have the overheads but I guarantee this guy gives you everything you ask for with a smile thank you Jay we will be using you again"

"I got a call from Kyle around 4:55 pm. He said he was able to come out around 7 pm, keep in mind, Hyper Flow closes at 5 pm. Kyle came out of his way after hours, ran a camera through my sewer line, snaked out the line, and then showed me on the camera the second time that the line was clearish. My main sewage line has been building up for a few years. Kyle gave me 3 different estimates for futures maintenance. I have already made an appointment for Kyle to come back out and do some more work. He is very up front, honest, and caring. He isn't just trying to get paid, Kyle is aware that life happens and works with customers to do what works best financially for the customer at the time of the job. I would recommend Kyle and Hyper Flow to anyone who is looking for a plumber with years of experience and has the best intrest for his customers."

"The toilets in one of our condominium rental units were backing up. We assumed that the line needed to be snaked. We calledAfford-A-Rooter and AJ came out to help us. After noting everything else was draining fine he realized it was the toilets themselves. Apparently, toilets build up a calcium deposit that can actually block flushing.. He told me what the problem was, and told me the best solution would be new toilets. It would have been as expensive to auger the crank toilets. He told me how much it would be if he were to do it, and, since I have replaced toilets in the past I told him I could do it myself. He agreed that would be the quickest and cheapest solution. He did not charge me anything for the service call. I appreciated his honesty and we will definitely use this company again."

Toilets FAQs, answered by experts

A running toilet is not a plumbing emergency, but you will want to try some DIY fixes or call in a plumber to prevent wasting gallons of water. The three most common causes of a running toilet are a broken or dirty flapper, an incorrectly sized chain between the flush lever and flapper, or a float that is out of position.

A high pitch noise after flushing is likely caused by the fill valve being clogged with debris. You can repair this and eliminate the noise by removing the fill valve from the tank, and then cleaning the valve screen. Place the clean fill valve back in the tank and flush as normal.

Yes, you’ll need to replace your toilet’s wax seal any time you move the toilet. This is because movement of the toilet will break the seal, rendering the remaining wax useless. Thankfully, replacing a wax seal is fairly easy, and the seal itself only costs $2 to $10 at most home improvement stores.

When replacing a wax seal you typically also have to replace the closet bolts that secure the toilet to the flange. These are usually about 2.5" - 3" long and have to be cut once the toilet is secure. Cutting them usually makes them too short to reuse.

You can DIY your toilet flapper replacement if you’re up for a small plumbing project. Turn off the water to the toilet, open the tank lid, remove the chain from the lever, and unhook the flapper. For a new, adjustable flapper, adjust it to the right setting according to your toilet's gallons per flush rating. Hook the flapper in place and install the chain with 1/2 inch of slack.

Some of the most common bathroom leaks include showers, sinks, and toilets. Most homeowners discover these leaks because of the chronic dripping sound faucets and showers make as water drips to the ground, but a leaky toilet will often appear as a puddle. Inspect your bathroom faucets, showers, and toilets every month to detect leaks quickly.
